A CORPORATION OF NEW YORK WINDOW FRAME AND SASH CONSCIIRTJ'CTION (REMOVABLE SASH) Application filed May 25,

bodying my invention.

Figure 2 is a frontelevation of parts seen in Figure 1.

Figure 3 is anvelevation of the removable strip.

Figure 4 is aplan view thereof.

This window construction comprises, generally, a frame element and a sash element, one of which is formed with a channel for receiving the other elementfone wall of the channel being detachable and means located within the width of the channel for holding the detachable wall in position and for pressing it toward the other element.

In the illustrated embodiment of my invention, the frame is the element formed with the channel for receiving the other element or sash.

1 designates the frame having a guide comprising'a body 2 formed with one side wall 5 3 of the channel.

4 is a strip forming the other side wall of the channel and 5 is the stile of the sash movable in the channel between the walls 3, 4. The removable wall of strip 4 is provided 4 with an angular arm 6 at its base extending in a direction crosswise of the channel, the arm 6 and the strip forming an angle lever fulcrumed near its angle. The means for acting on said lever or the arm 6 to press the strip 4 toward the sash 5 is located within the width of the channel and comprises a spring 7 pressing on the free end of the arm 6. There are usually several of these arms spaced suitable distances apart and a spring 7 corresponding to each arm 6. The arm 6 is also 1928. Serial m5. 280,401.

provided with means for interlockingwith if the body 1 in order to normally hold the strip 4 from displacement, this interlocking means being held in engagement by the spring 7.

The body 2 is preferably formed up of sheet metal to form the wall 3 and the bottom 8 of the channel, and also an outwardly extending flange 9 at the edge of the bottom remote from the flange 3. This flange also has an outwardly extending lip 10 resting on the frame 1. Also, the bottom is formed at suit able intervals with indentations 11 resting on the frame 1 and secured thereto as by screws 12. These indentations are for the purpose of coacting with the bolt of the sash holder. The body 2 of the guide is also preferably formed of sheet metal and folded upon itself to form the wall 3 so that the wall 3 is double and the spring 7 is a leaf spring with a base portion 13 clamped between thedouble portion of the wall 3 of the channel. The remaining portion of the spring extends crosswise of the channel beneath the bottom 8 thereof and is V shaped in cross section with its free end pressing on the arm 6. The apex of the V is toward the flange 9 in line with openings or slots 14 through which the arm 6 extends so that the arm 6 will engage the spring and tension it as the arms are passed through the openings 14 into the space beneath the bottom 8 when the strip 4 is being placed in position.

The strip 4 is also formed up of sheet metal with its inner marginal portion'bent upon itself to form a double wall and the arm 6 is one flange of an angle piece, the other flange 15 of which extends between the double walls of the part 4.

The strip is also formed with a lengthwise corrugation 16 at its base and the angle formed by the arm 6 and flange 15 rests at 17 on the inner face of the corrugation. The

outer margin of this corrugation fulcrums at 18 on the outwardly extending lip 10. Each arm 6 is formed with means for ratcheting into engagement with the wall of the slot 14 and as here shown, each arm is formed with a boss19 having an inclined face and an abrupt face, the inclined face engaging the wall of the slot when the arm 6 is being thrusted through the slot 14 causing the arm to move into engagement with a snap action.

The sash 5 may be of any suitable form, size and construction and the stiles thereof are usually formed up of sheet metal.

The sash and guide construction is of minimum Width andv the spring means, which presses the removable strip against the sash, is located within the width of the guide or channel.

To remove the sash, the strip 4 is detached by moving it with a prying tool inwardly against the tension of the springs until the bosses 19 clear the walls of the slots 14 and then pulling tightly laterally on the strips to Withdraw the arms 6 out of the slots. To replace the strip 4, the arms 6 are alined with the slots 14 and the strip pushed until the bosses 19 snap into engagement with the walls of theslots 14. V
